PUSH TRACTOR.

Application led December 17, 1920. Serial No. 431,477.

To all 'l0/0m it may concern.'

Be it known that l, Gor'rmnr, h/Lrr'ri-nrs, a citizen of the UnitedStates of America, residing at Beulah, in the county of Mercer andSta-te oit North Dakota, have invented new and useful improvements inPush Tractors, of which the following is a specifica-- tion.

rlhe object ol the invention is to provide a relatively simple pushtractor 'for use in connection with push headers and like agriculturalmachinery, and also as a means ot use as a stationary engine for drivingthreshers, feed cutters and the like, whereby a short or right angleturn of the header or other farm machinery may be e 'ected at thecorners ot the field in which such machine is being` operated; and withthis object in view the invention consists in the construction andcombination ot parts of which a preferred embodiment is shown in thedrawing wherein Figure 1 is a plan view ot the tractor.

Figure 2 is a. side view ot the same.

,lhe apparatus consists essentially of a lrame having` a push beam 1()adapted to operate in a position substantially parallel with the path ofmovement ot the tractor and oi: the agricultural machine in advancethereotwhich is beingV pushed by the tractor, a rearwardly divergentbase trame 11 extending from the io ward end ot the push beam, the rearportions of said push beam, and brace beam are provided `-ith bearings12 in which is mounted the drive shaft 13 carrying the traction wheels14 by which the apparatus is propelled:

Carried by the shaft 13 are the sprocket wheels 16 and 17 by whichmotion is comiunicated to the shaft. Forwar driving,r movement iscommunicated through the sprocket 17 by leans of a chain 15 which istrained thorcover and over a sprocket carried on the crank shaft 18 ot adriving unit 19 preferably of the internal combustion type. A clutch 2Ois provided to el'lfect and release the operative connection between thesprocket wheel 17 and the shaft 13, this clutch being under the controlof the operator of the machine through the medium of a hand lever 31.

The sprocket Wheel 16 is designed to impart rearward movement to theapparatus,

to vwhich end a chain 27 is employed which is trained over the sprocket1G and over a similar sprocket 25 mounted on a countershalt 23, thelatter being driven by the driving unit or motor 19 through theinstrumentality of a chain 26 which is trained over a sprocket 2lcarried at the adjacent end ot the countershaft 23, and over a sprocketmounted on the motor crank sha'lft 1S at `the end opposite the sprocketand carrying the chain 15. The sprocket drivingthe chain 26 is releasedfrom or may be fast to the crank shaft olf" the motor by means olf aclutch 21 operable by means of hand lever 8O disposed in position foractuation by the operator of the appara-tus. The chain 26, it will benoted, is crossed, so that movement in the opposite direction from thatin which the motor rotates is communicated to it. Thus when the clutch21 is employed, retrograde or rearward movement is imi'mrted to thedrive shaft 1.3 and hence to the traction wheels.

Steering` ot the apparatus is eliected through the instrumentality oit'a steering wheel ot' the castor type carried at the louf'er end oit asteering; post 2l by means oil which angular movement may be imparted tothe said steering` wheel.

Havingr described the invention, l claim:

A push tractor -tor the purpose indicated having' a frameconsisting-,oit a push beam. disposed for movement in parallelism withthe path oi' the machine and a rearwardltY divergent brace beam, a driveshaft mounted .in bearings at the rear end ont said push and bracebeams, traction wheels mounted upon said drive shaft, a motor carried bythe fra-me, a clutch controlled chain drive between the mot-or shaft andthe drive shalt, a countershat't mounted on the Ytrame and having adriving conn ion with the drive shaift and a. clutch controlled drivingconnection between the motor shaft and the countershait, the said latterconnection rotating; the countershaft reversely to the niotor shaft, anda steering wheel at the forward end or apex of the trame of the machine.

In testimony whereot` I aiix my signature.
